A further object of this inventionis to provide `a device of this kind having means whereby the frame side may not only be re` 'i moved without scratching of the ournals but may be replaced without scratching of the journals. f

A still further object of this invention is to provide a safe handling means for the relatively heavy parts comprising the truck frame of a railway car so that these parts can be handled without injury thereto or to the workmen.

The above and various other objects and 3o advantages of this invention will in part be described and in part be understood from the following detailed description of the present preferred embodiment, theV same being illustrated in the accompanying drawings, where- Figure 1 is a detail side elevation partly broken away vof a device constructed accordi ing tothe preferredembo'diment of this invention; y o

Figure 2 is aV longitudinal section taken substantially through the center thereof;

Figure 3 is a fragmentary front elevation taken on the line 3 3 of Figure 1; Figure 4 is a fragmentary side elevation partly in section of the frame side supporting brace mounted on the carriage;

Figure 5 is a sectional viewtaken on the line 5--5 of Figure 3. Y

Referring to the drawings wherein like numerals designate corresponding parts throughout theseveral views, the letter F C designates generally a frame structure of substantially U-shaped form and the numeral designates generally an upright frame :or support secured to this lower frame Ft'thisV support 10 being constructed in two parts one oneach sidepof the frame'F with the upper ends of each part disposedin spaced parallel relationto eachother. These uprights 10 are preferably, fconstructed in `substantially invertedlV-shaped form with one leg 11 thereof substantiallyfvertical and another leg 12 extending from fthe upper end of this vertical legll to the'end of the frameF. y In this manner, the vertical leg 11 will bel disposed intermediate each end of the frame F.y y Abeam B is mounted on a bar orshaft 13 extending'between lthe upper endsV of the opposedframe members 10 and this 'beam B has a substantially horizontally disposed upper endportion14 which is extended downwardlyfrom the bar `or mounting, as at 15,Y and the lower end of this extension 15 is se cured by means of a bolt or rivet 16 or the like to the rear end-of the frame F. This 7= beam B constitutes a portion of a crane and the length of Athis horizontal extension 14 is such as to extend slightly beyond the forward end of the frame F. A sheave 17 is mounted inthe forward end of the beam 14 and a cable or flexible member 18 is trained thereover and has secured to one end a link 19 which is provided with `depending loops or hooks 2,0 at each end thereof, the purpose for which will be hereinafterdescribed. l A drum 21 is mounted on a shaft 22 journaled in the upright frame members 10v and this shaft 22 has secured thereto a worm gear 23 which is engaged by a worm 24 jour naled yin the side Vof one frame member 10'.

VA bell crank 25 is secured to a shaft 26 rotatable with the worm 24 so that this Worm 24 may be rotated at a point rearwardly of the upright frame member 10.` The opposite parallel leg members 2'? and 28 of the frame membersF are provided at the forward ends thereof with a `downwardly opening notch 29 within which the rail 30 is received so as to not only support the forward end of the thel carriage frame F but also prevent lateral movement of this frame F with respect to the rail 30.

A transversely extending shaft 31 is journaled in the frame members 27 and 28 intermediate each end thereof and a pair of forwardly extending parallel guide members 32 are secured to this shaft 31 in spaced relation to each other and extend in the direction of the forward end of the frame F. A carriage C which is provided with slide members 33 engaging the guide rods 32 isslid`l tical position.

ably mounted on the guide'rods 32. Anoperating lever 34, which is rockably mounted as at 35 on the rear frameF and secured to:y

the horizontal connectingY bar 36 extending between the slides 33, is secured to the carriageC adjacent the middle thereof by means of a connecting link 37. In this manner, the rocking of the operating lever 34 will move on the guiderods 32.

' A pair of wedge blocks 381are removably mounted on the connecting Abar 36 and these wedge blocks have the upper surface thereof positioned in downwardly coverging relation so as to engage thetapering edgesfof the frame side Sso that when the side is engaged with the carriagewC, the-bottom of the side will reston the connecting bar 36 and the tapering sides will be engaged with these wedge blocks 38. The wedge blocks 38 have a' slot 39 to receive the connecting bar 36 and the sides of the block 38 are4 extended upwardly, as at 40, so Vasto engage on the opposite faces of the frame iside upwardly'from the bottom thereof and prevent lateral move ment of the frame side on the carriage C.

A substantially U-shaped brace ork support 41 hasV one leg thereof secured to the connecting bar 36 and the other leg is relativelyl short and provided with a laterally extending upper end portion 421for receiving a truck side supporting block 43. This supporting member 43 cooperates with the wedge vblocks 38 in holding the frame .side in upright or vertical position on the carriage C so that the carriage may be moved forward or backward on the guide rods 32. A rock shaft 44 extends between the frame members 27 and 28 adjacent the forward end thereof and inwardly ofthe slots 27 and is provided with Vcam members 45 for engagement with the guide members 32 so that when this shaft 44 is rocked, thelcam portions 45; will raise or lower the guide rods 32'and coactively raise-or lower the carriagerC.` Anv loperating lever 46 is secured vto one end of this rock shaft 44 and extends alongside one 0f the frame members. VThis lever 46is heldv in 'adjusted position by means ofa catch or rack member 47. j

j A shaft 48 extends between the parallel legs 27 and 28 inwardly of each end thereof and preferably adjacent the longitudinal center and Va pair of wheels 49 are journaled in wheel mountings 50'carried by this shaft 48. A lever 51 is secured to the shaft 48 and the rocking of this lever 51 will carry the wheels 49 into or out of engagement with the ground so that the frame F can be wheeled or rolled to the desired point. When the wheels 49 are in operative position, the lever 51 is in ,a position alongside the lower frame 'member 28 and is held in this position by means of a catch or latch member 52. When the wheels 49 are in inoperative position, the lever 51 is in substantially verj In the use of this device, the frame F may be wheeled or moved to the side o-f the car truck by. lowering the wheel carrying lever 51 so as to rock the shaft 48 and lower thel wheels49. The notches 29 of the frame members27 and 28 are engaged with the rail and in this position, the crane beam 14 will substantially voverlie the bolster of the wheel truck. The bolster engaging members 2O may Athen be secured to the bolster inwardly of the fra-me side S whereupon the drum 21 may Vbe rotated through the worm gea-r structure23 and 24 by rotating the bell crank 25, thereby raising the bolster to remove the springs, roller spring seat and rollers. The bolster may then be lowered sothat the end thereof will be positioned inthe wide opening of the side frame. The carriageC may then be raised in its forward position to engage and raise the side frame S whereupon the journal bearing wedges and journal bearings are removed. The wedge blocks 38 may be secured in position on each side off the carriage C and the frame side supporting member 43 put into position so as to prevent tilting of the frame side on the carriage C as it is moved vrearwardly by rocking the lever 34 rearwardly of the frame F. The movement of thecarriage C inwardly of the frame F will remove the frame side from the truck and thereby permit the replacing of the wheels and other parts pertaining thereto, which operation is performed without scratching the journals or bearings for the wheelaxes. In the adjustment'of the carriage C beneath the frame side, the cam shaft 44 may beraised or lowered to the desired point so that the guide bars 32 and thel carriage will be in the desired position beneath the frame side. When the wheels and other parts have been replaced, the frame side may then be moved forwardly by rocking the lever 34 which will move the carriage C toward be easily moved awaykfrom the wheels so as to permit the replacement of worn out wheels or other parts relating to the Wheel structure. In practice, there will preferably be two of these devices in use at one time, one on each side of the truck.
